What does (m>x m> ^ 0m>x m>1) != 0 mean?
...
The m>X m>OR operation (m>x m> ^ 0m>x m>1) inverts bit 0. So the em>x m>pression effectively means: if bit 0 of m>x m> is 0, or any other bit of m>x m> is 1, then the em>x m>pression is true.
Conversely the em>x m>pression is false if m>x m> == 1.
So the test is the same ...
